Abstract
Operating a respirator with an inspiration pressure-vs.-time curve (1), which has an airway target pressure (paw—target) and a PEEP (3), in which the inspiration pressure-vs.-time curve (1) reaches the airway target pressure (paw—target) on a ramp-like curve (17) starting from a starting airway pressure (paw—Start), which is greater than the PEEP (3).
Claims17
A process for operating a respirator with an inspiration pressure-vs.-time curve, which curve has an airway target pressure (paw—target) and a positive end-expiratory pressure (PEEP), the process comprising the steps of:
- forming the inspiration pressure-vs.-time curve from a starting airway pressure to the airway target pressure (paw—target) on a ramp-like pressure curve, the starting airway pressure (paw—Start) being greater than the PEEP.
A respirator for applying a inspiration pressure-vs.-time curve which has an airway target pressure (paw—target) and a positive end-expiratory pressure (PEEP), the respirator comprising:
- means for shaping the inspiration pressure-vs.-time curve, the inspiration pressure-vs.-time curve reaching the airway target pressure (paw—target) on a ramp-like curve starting from a starting airway pressure (paw—Start), the starting airway pressure (paw—Start) being greater than the PEEP.
A process for mechanically ventilating a patient, the process comprising the steps of:
- recording a PEEP (positive end-expiratory pressure) of the patient;
- providing an inspiration pressure/time curve;
- flowing breathing gas into the patient according to the inspiration pressure/time curve, the pressure/time curve transitioning from a starting airway pressure at a beginning of an inspiration stroke to an airway target pressure at an end of the inspiration stoke, the starting airway pressure being higher than the PEEP.
